Currently "--cc --dirstat" will show nothing for a merge. Like --shortstat and --summary in the previous two patches, it probably makes sense to treat it like we do --stat, and show a stat against the first-parent. This case is less obviously correct than for --shortstat and --summary, as those are basically variants of --stat themselves. It's possible we could develop a multi-parent combined dirstat format, in which case we might regret defining this first-parent behavior. But the same could be said for --stat, and in the 12+ years of it showing first-parent stats, nobody has complained. So showing the first-parent dirstat is at least _useful_, and if we later develop a clever multi-parent stat format, we'd probably have to deal with --stat anyway.
